The `NO_ERRORS_SCHEMA` schema can be used to ignore errors related to unknown elements or properties, but since it suppresses these errors it may also hide real problems in a template. This commit updates the `NO_ERRORS_SCHEMA` docs to mention that.
Closes#39454.

This is based on a discussion we had a few weeks ago. Currently if a component uses `ViewEncapsulation.ShadowDom` and its selector doesn't meet the requirements for a custom element tag name, a vague error will be thrown at runtime saying something like "Element does not support attachShadowRoot".
These changes add a new diagnostic to the compiler that validates the component selector and gives a better error message during compilation.

Previously we didn't document what versions were supported. Since universal requires node.js I'm adding version
information into the guide as a informative callout.

As previously discussed in pull/31070 and issues/30486, this would be useful because it is often desirable to apply styles to fields that are both `ng-invalid` and `ng-pristine` after the first attempt at form submission, but Angular does not provide any simple way to do this (although evidently Angularjs did). This will now be possible with a descendant selector such as `.ng-submitted .ng-invalid`.
In this implementation, the directive that sets control status classes on forms and formGroups has its set of statuses widened to include `ng-submitted`. Then, in the event that `is('submitted')` is invoked, the `submitted` property of the control container is returned iff it exists. This is preferred over checking whether the container is a `Form` or `FormGroup` directly to avoid reflecting on those classes.

We should primarily point readers to the stackblitz that contains the spec files and runs them.
The application stackblitz is secondary (and doesn't actually contain the spec files, which is confusing).

In the "Interceptor order" section of the HTTP guide there is a typo which incorrectly lists the same service twice when referring to two different services. The order that these services are listed is important, and this commit fixes the typo by listing the services in the correct order.

The documentation suggested that `@types/*` scoped packages would
automatically be recognized, however the CLI configures a project such
that the package has to be explicitly added to the TypeScript
configuration files.

Previously, the docs didn't say anything about the fact that the `novalidate` attribute is added to the enclosing form, or how to override that behavior. I have added a couple lines in the appropriate spot clarifying this issue.

This changes the example from "run an arbitrary process" to "copy a file". This should make it a bit easier to follow, require less background knowledge to understand, and not use any platform-specific commands that won't work for Windows users.
The most glaring issue with this change is that this doc does not explictly specify how to build and run a builder. I've updated some of the files to hint at this a bit more (such as the `"implementation": "./dist/my-builder.js"`), but another pass is required to figure out the best way to compile a builder and how we want to structure this example to best communicate that.

It turns out that we don't document anywhere how ngc works and what options we support.
I added a brief section, without going too much into details because most users should not need to use ngc directly.
I also came across some bug in `ngc` and filed #42372.

The faq on `forRoot` implies that you cannot and should not call `forRoot` for an import
outside the AppModule. This is technically incorrect. This commit clarifies
